I made a mistake and updated, from 4.2u to 4.3u (Cod: black ops disc upadte)

I appologise, if I am posting in the wrong place.

I went to purchase Call of Duty: Black Ops, for wii. Put in the disc, backed it up, with the usbloader. I tested it, the game wouldn't load. I restarted my wii, and loaded the game, through the system menu. I find out that he game wants me to update, before I can play the game. Instead of declining the update, I made a mistake and pressed the update button. I didn't want to risk bricking my wii, by unplugging the system, so I let it finish.

The wii didn't brick from the update, the homebrew channel was still on my system menu, the usbloader channel was still up... But when I when the usbloader, I got the black screen,with all of the white numbers and stuff on it. I'm guessing the 4.3 update is responsible for this.

I just want to know: Is there a way I can get it back to working the way it was? The homebrew channel doesn't seem effected at all. It's just the usbloader. Is there anything I could do, without bricking my system or should I just give up on this?

Pay special attention to Priiloader --- make sure you install it. This will prevent "accidents" from happening. Also be aware, there's a guide for this game; any questions on the guide go in that thread. Any questions on the softmod go in that thread. HBC works? Hooray. Your cIOS is gone. Please resoftmod.
